FAQ: Self-Employment Tax Calculator
What is self-employment tax?
It’s the tax paid by individuals who work for themselves. It covers Social Security and Medicare contributions, normally split between employee and employer — but when you’re self-employed, you pay the full amount (15.3%).
Does this include state income taxes?
No. This calculator estimates federal tax only. You should also check your state’s self-employment tax requirements.
Is the tax compounded monthly?
No. Self-employment and income taxes are calculated annually, based on your total yearly income.
What if I have deductions like home office or retirement contributions?
This calculator gives a basic estimate. For deductions and detailed planning, consult a tax advisor or use professional software like TurboTax or QuickBooks Self-Employed.
Can I use this calculator for quarterly tax planning?
Yes — divide your annual result by 4 to estimate what to pay each quarter to the IRS (via Form 1040-ES).
